Cop-turned-TV reporter Mike Sheehan was reined in at a Manhattan court yesterday after a bizarre — and allegedly drunken — fender-bender with an NYPD horse in TriBeCa.

Sheehan, 60, a senior Fox 5 correspondent, was arrested late Monday after colliding with the animal, named Manhattan, who was being ridden against traffic on North Moore Street by Officer Michael Loiacono, police said.

“What’s the matter? I didn’t hit nothing,” Sheehan said, according to the criminal complaint.

Following the crash — which bruised Loiacono’s leg, left the horse with cuts to his hindquarters, and shattered the driver’s-side window of Sheehan’s 2008 Mercury — the newsman refused to take a sobriety test, police said.

He was charged with driving while intoxicated, reckless driving and reckless endangerment, all misdemeanors.

Today, Sheehan said he did nothing wrong. “That’s all I’ve got to say. I’ve got to talk my attorneys,” he said as he left his Tribeca apartment.

His lawyer, Thomas Monaghan, said yesterday that the cops have it all wrong.

“How do you hit a horse with the side of your car? You can’t,” he said. “It’s Mr. Sheehan’s position that the horse ran into his car.”

Monaghan showed reporters the initial police report, in which arresting Officer Charles Zucconi noted that Sheehan’s breath did not smell of alcohol, his speech was not impaired, his eyes were clear and his balance steady.

At first, Sheehan was charged only with injuring a police animal, but “something happens and it morphed into this,” Monaghan said.

The next morning, Zucconi told prosecutors that “the defendant was intoxicated,” and had “slurred speech and the smell of alcohol on his breath.”

Lawyer Michael Dowd, who visited Sheehan at the First Precinct shortly after his arrest, said the newsman did not appear drunk at all.

“He seemed totally normal. I have no idea from where the charges of driving while intoxicated came from,” he said.

Before becoming a newsman, Sheehan was a decorated detective and spent 25 years on the force.
